Before you install
- Requires Python 3.7, 3.8, 3.9, or 3.10.
- Installation may require a C compiler and build tools if wheels are not available for your platform.
- Medium install friction due to compiled wheels for multiple Python versions (3.7, 3.8, 3.9, 3.10) and architectures (x86_64, aarch64, macOS).

What it is and what it does
Pyston-autoload is a thin wrapper that automatically loads and activates Pyston, a JIT compiler extension for Python, when your Python process starts. Pyston is available as a lite extension module that adds just-in-time compilation to Python 3.7, 3.8, 3.9, and 3.10 without requiring you to switch to a different Python interpreter—it works alongside your existing Python installation and is designed to be compatible with standard CPython binary packages.
The autoloader eliminates the need to manually enable the JIT in your code; once installed, it runs transparently. According to the project, the JIT delivers roughly 10% faster execution on web-serving macrobenchmarks. Installation is straightforward via pip, though the package itself has not been updated since September 2022.
Use it for
- Speed up web servers or long-running Python services without rewriting code or switching interpreters.
- Accelerate CPU-bound workloads in data processing or scientific computing that cannot easily use compiled alternatives.
- Test whether JIT compilation helps your application's performance before committing to a full interpreter switch.
- Reduce compute costs by improving throughput on existing Python codebases with minimal deployment changes.

pyston-autoload on PyPI
Before you install
Medium install friction due to compiled wheels for multiple Python versions (3.7, 3.8, 3.9, 3.10) and architectures (x86_64, aarch64, macOS). The package depends on pyston, which is a compiled extension. No active maintenance since September 2022, though the underlying repository shows recent activity.
Requires Python 3.7, 3.8, 3.9, or 3.10. Installation may require a C compiler and build tools if wheels are not available for your platform.
